Hannah Anderson's aunt speaks

Does Amber Alert suspect have IEDs?

The next day, the bodies of her mother, Christina Anderson, and 8-year-old brother, Ethan, were found about 45 miles east in DiMaggio's burned house in Boulevard.

That horror spurred a manhunt, which zeroed in on central Idaho after two critical clues: the discovery of DiMaggio's blue Nissan Versa outside the city of Cascade and a sighting of the pair by horseback riders.

One of the horseback riders on Sunday described multiple "red flags" that were raised during their brief interaction with the pair, including their brand-new camping equipment and the pajama-like bottoms Hannah was wearing.

Mark John recalled the interaction as "just like a square peg going into a round hole. They didn't fit."

Another rider, Mike Young, said it looked like Hannah "had a scared look on her face," adding about DiMaggio: "I just had a gut feeling about him."

Unaware of the Amber Alert, however, the horseback riders continued on, and only after seeing a news report on the pair upon returning home did the group put the puzzle pieces together.

"When I seen that picture on the screen, I told my wife, I said, 'That is the girl that was up on that mountain,'" John recalled.

Hundreds of law enforcement agents scoured 300 square miles of rough terrain, hampered by the smoke from nearby wildfires.

Late Saturday afternoon, they spotted the pair's campsite near Morehead Lake, Idaho. But the topography was so steep, helicopters had to drop authorities off far away from the camp.

Hostage rescue teams had to hike more than two hours to get to the scene, local sheriffs' departments said.

They moved in carefully so they wouldn't alert DiMaggio that they were coming.

"Once the teams set up, they waited until DiMaggio and Hannah separated and moved in," the Valley and Ada county sheriffs' offices said.

Authorities ushered Hannah to an area where a helicopter could whisk her away.

At some point, a "confrontation" ensued between authorities and DiMaggio, San Diego County Sheriff Bill Gore said. The confrontation ended when an FBI tactical agent shot and killed the murder and kidnapping suspect.

"Obviously we would have liked for Mr. DiMaggio to surrender and face justice in the court of law," Gore said. "But that's not going to be the case."

'Hannah is safe'

Hannah didn't appear to have significant physical injuries,but was immediately taken to a hospital, the sheriff's spokeswoman said.

"Hannah is safe, and that was our first priority from the very beginning," Valley County, Idaho, Sheriff Patti Bolen said.

In his text to CNN, Brett Anderson expressed a range of emotions upon hearing of his daughter's rescue soon after his wife and son's death.

"I am nervous excited saddened 4 my wife and son and worried what my daughter has been through," he wrote.

But Hannah did not want to be alone with DiMaggio after that, Chavez said.

"I don't think she would have gone willingly with him at all," she said.

In an earlier episode, Chavez recalled a trip that DiMaggio and Hannah took to Hollywood. The trip was supposed to be for one week, but Hannah told Chavez that they came back after two days because DiMaggio was upset that she wasn't paying enough attention to him.

Search intensified after car spotted

DiMaggio's car was found after John reported he had a brief conversation with two campers in the Idaho wilderness on Wednesday.

Grief over the deaths of Hannah's mother and brother gave way to euphoria after the teen was found alive.

"We're very excited," Sara Britt, Hannah and Ethan's grandmother, said Sunday. "Just ecstatic. Jubilation. We couldn't ask for anything more. This is the outcome we wanted."

But the outcome was also bittersweet for Britt and her husband, Ralph, who lost their daughter Christina and grandson Ethan in the ordeal.

Asked whether she had any sense that DiMaggio might have been capable of the alleged crimes, Sara Britt said never.

"Even the way it turned out -- I mean he loved little E, and he loved my daughter, and for him to do such a horrific act, it's just not fathomable. I can't understand it because he loved them too," she said.

Ralph Britt said he wants Christina to be remembered "as a daughter and a mother of two great kids. That's it."
